| 词条 | Force meter |
| 释义 |
A force meter is an instrument to measure the magnitude of a force. This is often just a spring contained within a cylinder that has a scale to mark the extension of the spring produced by the force. In the International System of Units, the unit of force is the newton (symbol N). A force meter that measures force in newtons may be referred to as a newtonmeter. A spring-based force meter with uniformly marked scale intervals relies on Hooke's law, which states that the extension or compression of a spring is proportional to the applied force. See also
